Revert "mm: Always release pages to the buddy allocator in memblock_free_late()." (2023-02-07 13:07:37 +0200)
----------------------------------------------------------------
Revert "mm: Always release pages to the buddy allocator in memblock_free_late()."
This reverts commit 115d9d77bb0f9152c60b6e8646369fa7f6167593.
The pages being freed by memblock_free_late() have already been
initialized, but if they are in the deferred init range, __free_one_page()
might access nearby uninitialized pages when trying to coalesce buddies,
which will cause a crash.
A proper fix will be more involved so revert this change for the time
being.
